Shader FX - vertex alpha broken?

Eric Chadwick

I can't seem to get Shader FX to use vertex alpha. Is this broken in Max 2016?

Vertex alpha is working when I use Object Properties to preview it, but not if I wire it into a shader.

Am I just missing something basic?

I think you have to set the index to 1 on the vertex color node and then use r,g or b.
If i remember correctly

Vertex Color Set Name on the Vertex Color ShaderFX node has to be set perhaps? I think that's the case with the Maya equivalent if I'm not mistaking.

Yep, it was setting the Index to 1, and using r, g, or b.

Might be a good thing to add to the Help file, so I added a comment in there. Hopefully it ends up in the Help popup!

Thanks you guys!
